Could Putin attack Britain by blocking the SUN? Fears hostile actors might deploy 'weather weapons' as ministers order probe into 'risks'

Foreign states could 'create chaos' by dimming Britain's sun and orchestrating a natural disaster, ministers have been warned.
There are fears hostile actors such as Russia could make use of solar engineering technology to reflect light away from the earth and back into space.
The concept - using techniques such as deploying aerosols into the atmosphere to reflect light back into space - has been mooted as a way of limiting global warming.
However, experts say that comes with major risks - and concerns have been raised within government that it could be abused by 'an independent or third-party actor'.
Net Zero minister Kerry McCarthy wrote in a letter: 'The UK is a longstanding leader on climate action and an active international collaborator in scientific research.
'The Government recognises the need to understand the risks and impacts of [solar radiation modification] approaches that could be deployed by an independent or third-party actor.'
In the letter seen by The Telegraph, she added: 'Robust scientific evidence is essential for informing responsible and inclusive governance.'
Aria - the government's advanced research and invention agency - has allocated £50million in funding for outdoor field trials, which include brightening clouds to reflect sunshine
Matt Ince, associate director at Dragonfly Intelligence, said Vladimir Putin's Russia was 'increasingly expanding its use of hybrid warfare activities'.
He cautioned geoengineering may be seen as a desirable option due to its 'relative affordability' and the 'feasibility of conducting it' and added some sort of intentionally orchestrated environmental disaster' is an 'avenue that Russia may pursue'.
Such tactics could 'create chaos and a sense of discord, and force countries to become more inward focussed'.
It comes as more than 560 academics have signed an open letter calling for an 'international non-use agreement' on solar geoenginering.
The letter states that without the limits the resulting geopolitics could be 'frightening and inequitable'.
Aria - the government's advanced research and invention agency - has allocated £50million in funding for outdoor field trials, which include brightening clouds to reflect sunshine.
However, the government is not proposing to deploy it for 'climate cooling'.
An Aria spokesman said: 'In line with the Government's position on SRM deployment, Aria is not funding deployment, and does not support, the deployment of any climate cooling approaches.'
The agency aims to 'unlock scientific and technological breakthroughs that benefit everyone'.
'We empower scientists and engineers to pursue research that is too speculative, too hard, or too interdisciplinary to pursue elsewhere,' it says on its website.
The research agency was originally the brainchild of Dominic Cummings, Boris Johnson's former chief aide, and was set up in 2021 by ex-Tory business secretary Kwasi Kwarteng.
The body, based in London, has been given a staggering £800million budget – of taxpayers' cash – to go towards 'high-risk, high-reward' scientific research.
A Government spokesman said: 'The government is not in favour of using solar radiation modification, but we support cautious, controlled research aimed at improving our understanding of its risks and impacts.

Hundreds protest in The Hague against NATO, days before the Dutch city hosts alliance summit

Hundreds of people protested Sunday against NATO and military spending and against a possible conflict with Iran, two days before a summit of the alliance in The Hague that is seeking to increase allies' defense budgets. 'Let's invest in peace and sustainable energy,' Belgian politician Jos d'Haese told the crowd at a park not far from the summit venue. Although billed as a demonstration against NATO and the war in Gaza, protesters were joined by Iranians who held up banners saying 'No Iran War,' the day after the United States launched attacks against three of Iran's nuclear sites. 'We are opposed to war. People want to live a peaceful life,' said 74-year-old Hossein Hamadani, an Iranian who lives in the Netherlands. Look at the environment. 'Things are not good. So why do we spend money on war?' he added. The Netherlands is hosting the annual meeting of the 32-nation alliance starting Tuesday, with leaders scheduled to meet Wednesday. The heads of government want to hammer out an agreement on a hike in defense spending demanded by U.S. President Donald Trump. The deal appeared largely done last week, until Spain's Prime Minister Pedro Sánchez wrote to NATO Secretary General Mark Rutte that committing Madrid to spending 5% of its gross domestic product on defense "would not only be unreasonable, but also counterproductive.' U.S. allies have ramped up defense spending since Russian President Vladimir Putin ordered a full-scale invasion of Ukraine more than three years ago, but almost a third of them still don't meet NATO's current target of at least 2% of their gross domestic product. The summit is being protected by the biggest ever Dutch security operation, code named 'Orange Shield," involving thousands of police and military personnel, drones, no-fly zones and cybersecurity experts. ___ Associated Press writer Molly Quell in The Hague contributed.

British rocket launch backed by Labour falls further behind in space race

A British rocket start-up backed by Labour has pushed back the date of its first launch and is hunting fresh funding as the UK faces falling further behind in the space race. Orbex, which in January received a £20m investment from the taxpayer, confirmed its first test launch from the Shetland Islands would be in 2026, rather than later this year as hoped. The start-up is building its 62ft Orbex Prime rocket at a factory in Scotland, which is intended to carry small satellites into space. After securing taxpayer support, Orbex is now seeking a further £120m in funding from private investors over the next four years to bring its ambitions to reality, it said in a submission to MPs. The company is also pushing for further government backing, calling for support for its bid to build a new, larger rocket for the European Space Agency. The space organisation, of which the UK is a member, is offering companies up to £144m for its European Launcher Challenge as Europe seeks alternatives to its current reliance on Elon Musk's SpaceX. Orbex has been lobbying for Labour's £7bn National Wealth Fund to back the space sector, which it said in a consultation filing to MPs could 'level the playing field and unlock significant value for the UK economy'. The delay to Orbex's mission comes after a series of setbacks for Britain's fledgling launch industry. After a failed launch from Cornwall in 2023, Sir Richard Branson's Virgin Orbit went bankrupt. Since then, no new attempts at an orbital mission have gone ahead. Now, a number of small rocket companies are seeking to launch from UK soil, largely from Saxavord, a spaceport on the Shetland Islands, although they have faced delays. German start-up, Rocket Factory Augsburg, is still targeting a mission this year from Shetland, although its last test ended with its rocket exploding on the launchpad. Skyrora, a Scottish start-up, is hoping to launch from Shetland next year. A spokesman for Orbex said: 'There are many factors at play in determining our launch schedule, including licensing and launch logistics. This is not unusual.' The spokesman added government support would be needed to build a European rocket: 'National funding commitments and private investment will both be needed for winning bidders. 'UK Government support for our sector will send a clear signal to ESA that UK orbital launch companies like Orbex are a smart choice and long-term partner.'

Palestine Action member says potential ban ‘absurd'

A Palestine Action member has said the governments plans to proscribe the group, effectively branding them a terrorist organisation is "absurd." Saeed Taji Farouky said it "rips apart the very basic concepts of British democracy and the rule of law... something everyone should be terrified about." It is understood the home secretary is preparing a statement to put before Parliament on Monday, after Palestine Action activists broke into RAF Brize Norton in Oxfordshire and sprayed two planes with red paint. Farouky said Palestine Action's "whole reason for being is to break the material supply chain to genocide" and said Friday's incident was an "escalation in tactics because the genocide has escalated". Israel continues to deny allegations of genocide relating to the ongoing war in Gaza.
